Quoted from this link - "The assassination of John F. Kennedy in 1963, perhaps more than any other single event, defines the time at which Americans began to seriously doubt the reliability of what the government tells us. From that point on, the public gradually lost trust in government, our institutions and our elected officials. This has been an ongoing public relations problem for the government and its agencies, in light of other assassinations, revelations of spying on American citizens and the various political scandals in the years since 1963."

Quoted from me - Not that i don't enjoy this article but the first time Americans doubted the government was when we wrote a document exposing all of the lies and abuse the government was doing to us and we said we are now free of you, go away. That was the Declaration of Independace!! :-D :-D :-D
